Ok. I have a machine here which triggers somethign similar to this pretty often. For me udev finds /dev is read-only and halts boot. This is presumably because our devtmpfs /dev has not made it into / when it starts. I was getting a failed boot about every 5-6 boots, 4 in 20 overall. I then used the work around in comment #54, with that in place I have 35 consecutive successful boots.
The conjecture is that /dev in the initramfs is busy and cannot be moved when needed. From the ps output in comment #57 it seems udev has not actually quit when requested, which might well account for this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/818177 Title: boot failures caused by udev race To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/818177/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
